Expression data from mouse muscle

ABSTRACT: The knock-out of calpain 3 (C3KO) is a murine model for calpainopathies wich shows a mild dystrophic phenotype with signs of muscle degeneration. Adult (A) mice show a more severe phenotype than young (Y) mice which only present inflammatory infiltrates in most severely affected muscles, such as the soleus. Other muscles (e.g. quadriceps) are much less affected. We used microarray technology to compare gene expression profiles of young and adult muscles in wild-type (wt) and C3KO mice, in two types of muscle: soleus (affected) and quadriceps (much less affected). 11 wt (7 adult and 4 young) and 11 C3KO (7 adult and 4 young) mice were used in this study for RNA extraction and hybridization on Affymetrix microarrays. The soleus and the quadriceps muscles were obtained from each mouse. All mice were males.

Effect of muscular dystrophy caused by PTRF deletion on the transcriptome of skeletal muscles

Project description:Muscular dystrophy is a group of diseases that cause progressive weakness and degeneration of the skeletal muscles that control movement. Lacking the caveolae component polymerase I transcription release factor (PTRF) causes a secondary deficiency of caveolins resulting in muscular dystrophy. To investigate the effect of PTRF deletion on skeletal muscle, we created gene-edited mice with PTRF knockout (KO). We then performed RNA-seq of soleus and quadriceps muscles from soleus and quadriceps muscles of 3 months old WT (n=3) and PTRF KO mice (n=3) and analyzed the data for gene expression profiling. 12933 genes were detected across all 12 libraries. The hierarchy clustering of co-expressed genes revealed a clear split between PTRF KO and WT mice for both skeletal muscles. Differential expression analysis identified 1293 and 705 differentially expressed genes (DEGs) in the soleus and quadriceps, respectively. 971 and 534 DEGs were up-regulated, and 322 and 171 DEGs were down-regulated in the soleus and quadriceps of PTRF KO mice, respectively.

Muscle-specific cellular and molecular adaptations to late-life voluntary concurrent exercise in mice [NovoGene]

Project description:Aged mice (22-24 mo) underwent Progressive weighted wheel running (PoWeR) for 8 weeks. RNA-seq on soleus and plantaris muscles was conducted on untrained and PoWeR trained mice. RNA from soleus and plantaris of young mice (4-6 months old) was used as a comparator (Englund et al. 2021 Function)

MiRNA expression profiling of skeletal muscles in aged rodents

Project description:Skeletal muscle atrophy is one of the critical issues which elderly people face. The precise mechanism underlying muscle atrophy during aging is not fully understood. In order to identify miRNA whose expression is changed in age-associated muscle atrophy, we performed miRNA expression profiling of skeletal muscles in young and aged rats. Microarray analysis revealed differential miRNA expression in EDL and soleus muscles of aged rats compared with those of young rats. We next investigated whether the age-associated changes of miRNA expression observed in rats were recapitulated in mice and found that the expression level of miR-206 in EDL muscle and that of miR-196a in EDL and soleus muscles were respectively higher and lower in aged rodents than in young rodents. In mouse C2C12 myoblasts and myotubes, introduction of miR-196a decreased the protein level of Forkhead-box transcription factor Foxo1, a known target of miR-196a, indicating that miR-196a may regulate Foxo1 expression also in skeletal muscles. Furthermore, miR-196a overexpression exacerbated cell death caused by an exposure to hydrogen peroxide. Lastly, we demonstrated that expression of Foxo1 was elevated in EDL and soleus muscles of aged mice compared with those of young mice. These results suggest that miRNAs are involved in skeletal muscle atrophy during aging and that decreased miR-196a expression may protect skeletal muscle cells from oxidative stress in part through induction of Foxo1.

Differences in gene expression between fast and slow muscle or between normal and denervated slow muscles

Project description:Fast and slow skeletal muscles show different characteristics and phenotypes. This data obtained from microarray includes the comparison of normal fast plantaris and slow soleus muscles of adult rats. Characters of slow muscle are strongly dependent on the level of muscular activity. Denervation silences the muscular activity. Therefore, we determined the effects of denervation on gene expression in slow soleus muscle of adult rats.

Transcriptomic analysis of mdx mouse muscles reveals a signature of early human Duchenne muscular dystrophy

Project description:The mdx mouse (C57BL/10ScSn-DMDmdx/J), like Duchenne muscular dystrophy (DMD) patients, lacks the protein dystrophin. However, the mdx mouse has a normal lifespan and mild pathology while DMD remains a severe, fatal disease. New mouse models have been developed that are more severely affected but they have not replaced the mdx mouse in DMD research. A few years ago RNA-sequencing (RNA-seq) results of biopsies from DMD and normal human muscle were published but we could not find equivalent data for the mouse. We now report RNA-sequencing of three wild-type and mdx mouse muscles: the flexor digitorum brevis (FDB), the extensor digitorum longus (EDL), and the soleus (SOL). The FDB, a plantar foot muscle is often used for in vivo and ex vivo experiments but may be less affected by the lack of dystrophy than the hindlimb muscles. We compared muscles from 2- and 5-month old mice to investigate the time-course of the mdx pathology. The results show a muscle- and age-dependent parallel between mdx and DMD muscles. Although the FDB is less affected than EDL and SOL at 2 months, the three muscles show, at both ages, activation of close to 100 genes from 7 pathways that are affected in presymptomatic DMD patients and have been called "DMD disease signature".

Project description:The study used liquid-chromatography tandem mass spectrometry (LC-MS/MS) combined with bioinformatics analysis to analyze muscle biopsies from the vastus lateralis muscles obtained from two groups of young males after four weeks of either concentric or eccentric resistance training of the quadriceps femoris muscles.

Identification of cold-shock protein RBM3 as a possible regulator of skeletal muscle size

Project description:The goal of this study was to identify changes in muscle gene expression that may contribute to loss of adaptability of old muscle. Muscle atrophy was induced in young adult (6-month) and old (32-month) male Brown Norway/F344 rats by two weeks of hind limb suspension (HS) and soleus muscles were analyzed by cDNA microarrays. We conclude that a cold shock response may be part of a compensatory mechanism in muscles undergoing atrophy to preserve remaining muscle mass and that RBM3 may be a therapeutic target to prevent muscle loss.
